The invention relates to the technical field of stem cell preparation, and provides a sterile operation device for stem cell preparation, comprising a base and an operation box fixedly mounted on the base, wherein an inlet and outlet groove is provided at the bottom of one end of the base, a rising groove communicating with the inlet and outlet groove is provided at the middle position of the top of the base, an inlet and outlet communicating with the rising groove is provided at the middle position of the bottom of the operation box, a side groove is provided at one end of the rising groove, and a ventilation cavity is provided inside the top corner of the base; a placing frame is arranged to fit inside the inlet and outlet groove. The invention ensures that the operation area is in a sterile environment, is convenient for taking and placing stem cell storage containers, is convenient for replacing sterile air in a small ventilation area, avoids the problem of long-term contact and contamination of stem cells with bacteria, and hinders the entry of sterile air into the operation device, avoids the contact of stem cells with bacteria at the first time.

The utility model discloses a water and soil loss prevention and control frame, which comprises a connecting frame and a filter screen, a connecting plate is arranged in the middle of the connecting frame, a built-in cavity is arranged in the connecting plate, the filter screen is arranged in the built-in cavity, a connecting frame is arranged in the connecting frame, a connecting water pipe is arranged on the inner wall of the connecting frame, and the connecting water pipe is connected with the connecting plate. A reinforcing plate is arranged on the bottom face of the connecting plate, and a ground pile is installed at the bottom of the reinforcing plate. According to the water and soil loss prevention and control frame, through clamping connection between a filter screen and a built-in cavity, the filter screen can be conveniently limited, when the built-in cavity receives rainwater, the filter screen can filter and intercept the rainwater, impurities in the rainwater are effectively intercepted, the impurities are prevented from entering a connecting water pipe, a ground pile can penetrate into soil, and the water and soil loss prevention and control frame is convenient to use. And the waterproof film can play a role in preventing permeation, so that the bottom surface of the connecting frame can be prevented from being in contact with water for a long time, and the connecting frame is prevented from being damaged.

The circuit breaker comprises a circuit breaker body, a slot is arranged in the circuit breaker body, a placing box used for storing writing paper is movably connected in the slot, a sealing ring is fixedly connected to the inner side of the left end of the placing box, and a sealing groove is formed in the position, corresponding to the sealing ring, of the right side of the circuit breaker body. A transparent plate is fixed to the position, corresponding to the slot, of the front face of the circuit breaker body, the right side of the circuit breaker body is rotationally connected with an elastic pressing piece, the elastic pressing piece can abut against the right end of the containing box after rotating, and the upper side, the lower side and the left side of the inner wall of the containing box are fixedly connected with grid blocking strips for limiting writing paper. Writing paper placed in the placing box can be sealed and isolated through the inserting groove, the placing box, the sealing ring and the sealing groove, and the situation that information on the writing paper is blurred and cannot be seen clearly by workers due to the fact that the writing paper makes contact with air for a long time and is wetted by water vapor in the air is avoided.

The utility model discloses a sterile auxiliary device for peritoneal dialysis. The sterile auxiliary device comprises a sealing layer, a fixing layer, an attaching layer and an outer membrane layer which are sequentially stacked, the sealing layer is provided with a sealing strip hook face and a butt joint sterile top face, an inlet tube fixing strip and an outlet tube fixing strip are arranged on the two sides of the fixing layer and are respectively provided with a front face and a back face, the attaching layer is provided with a front face and a back face, and the front face of the attaching layer comprises a sealing strip rough face, a butt joint sterile bottom face, a peritoneal dialysis tube inlet port bottom pad and a peritoneal dialysis tube outlet port bottom pad. The sealing strip rough face of the attaching layer is matched with the sealing strip hook face of the sealing layer, the back face of the attaching layer is a bonding face, the outer film layer is provided with a bottom bonding pad, and the bottom bonding pad of the outer film layer is matched with the bonding face of the attaching layer. According to the peritoneal dialysis catheter, the risk that the joint of the peritoneal dialysis catheter and the external short tube is contaminated by bacteria in the peritoneal dialysis liquid changing process can be effectively reduced, the situation that the catheter is pulled accidentally from the outside in the liquid changing process is avoided, and the standardization and accuracy of liquid changing operation are effectively improved.

The application provides a method for starting and running an access connector system of a trusted data space, and belongs to the field of data security.The method comprises the following steps: reading an encrypted business system image corresponding to a version of a preset starting configuration from a storage area according to the starting configuration; obtaining a temporary decryption key for decrypting the encrypted business system image; performing a decryption operation on the encrypted business system image based on the temporary decryption key to obtain a business system, and destroying the temporary decryption key after the decryption is completed; creating a memory file system in the memory; loading the business system to the memory file system; switching a system root directory to a business system root directory in the memory file system; and starting the business system.The application realizes the protection of the overall business system running environment, avoids the long-term existence of the core business logic in the form of plaintext in the storage medium during the system running, and significantly improves the ability of the business system to resist copying, reverse and tampering.
